What else can I help you with?
When ammonium chloride mixes with water the solution formed feels cold what type of reaction is this endothermic or exothermic?
When ammonium chloride dissolves in water, it is not a reaction at all, but only a dissolution. Since the solution formed feels cold, the dissolution is endothermic, absorbing heat from its surroundings.
What are the 3 stages of manufacturing sodium chloride?
- dissolution of impure solid sodium chloride - filtration - refining
Is the dissolving of sodium chloride in water endothermic or exothermic reaction?
The dissolving of sodium chloride in water is an exothermic reaction because it releases energy in the form of heat.
Chemical reaction between sodium chloride and water in which sodium chloride is the reactant?
Sodium chloride doesn't react with water; after dissolution NaCl is dissociated in Na+ and Cl-.
if sodium chloride dissolves in water what is it a chemical or physical change?
The dissolution of sodium chloride in water is considered a physical change because no new substances are formed - the sodium chloride remains as sodium and chloride ions in the water solution.
Why should sodium chloride be mixed in water?
By mixing the time of dissolution is reduced.
Is Calcium chloride in water is endothermic or exothermic?
The dissolution of calcium chloride in water is exothermic, meaning it releases heat. This reaction results in an increase in temperature of the solution.
Is dissolving sodium chloride a chemical or physical change?
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
Can you name another compound whose dissolution will be endothermic?
Dissolution for most substances is endothermic.
Why is NaCl plus H2O a physical?
Dissolution of sodium chloride in water is a chemical process.
Is NaCl an exothermic or endothermic reaction?
Only with very high heat. This compound can melt without decomposition.
Dissolution rate of normal saline?
The dissolution rate of normal saline, a solution of 0.9% sodium chloride (NaCl) in water, is typically rapid due to the high solubility of sodium chloride in water. When added to water, the salt dissociates into sodium and chloride ions almost instantly, resulting in a homogeneous solution. The rate can be influenced by factors such as temperature and agitation, with higher temperatures and stirring generally increasing the dissolution rate.
